چکیده انگلیسی
CdS thin films have been grown on Si(1Â 1Â 1) and quartz substrates using femtosecond pulsed laser deposition. X-ray diffraction, atomic force microscopy, photoluminescence measurement, and optical transmission spectroscopy were used to characterize the structure and optical properties of the deposited CdS thin films. The influence of the laser fluence (laser incident energy in the range 0.5-1.5Â mJ/pulse) on the structural and optical characterizations of CdS thin films has been studied. The results indicate that the structure and optical properties of the CdS thin films can be improved as increasing the per pulse output energy of the femtosecond laser to 1.2Â mJ. But when the per pulse output energy of the femtosecond laser is further increased to 1.5Â mJ, which leads to the degradation of the structure and optical properties of the CdS thin films.
